Just wanted to drop you a quick note about a tool called Omnivore, and it's pretty cool because it seamlessly integrates with both Obsidian and Logseq. If you're like me and love keeping your notes and highlights organized, you'll appreciate how it automatically converts your highlights into notes through the respective plugins.

As much as I would like these features, I still have to admit that this integration is NOT one of the most important features for me at the moment ;-)

But Ominivore would also be worth a look to see how they have implemented the transfer of article content for later reading. Highligthing of text parts is also supported there. Maybe it helps with the implementation of some ideas in stacks?
